BORGES-GARCIA, Misterbino et al. Creole clone yam from air bulbils production. Agron. Mesoam [online]. 2018, vol.29, n.1, pp.80-90. ISSN 2215-3608.

The employment of air bulbils in yam plants, like plantation material, allows using a 100% of the tubers crop for its consumption, the aforementioned implicates a significant agronomic, economic, social, and environmental impact. The aim of this study was to evaluate the main morphological and agronomic indicators of Creole clone yam in vitro plants obtained by using air bulbils during a first cycle field cultivation as a local level seed source. The research was developed in the Biotechnology Studies Center Plant at Granma University in collaboration with the localities of “Las Tamaras” and “La Asunción” between April and December, 2014. At thirty days, the survival percentage and morphological analysis (stem diameter and length/wide leaf ratio) of 1, 4 and 7 months plants were determined under field conditions (twenty plants by treatment). The agronomical analysis was carried out when the plants of the plantation were nine months, and the following variables were determined: tubers per plant number; tubers plant fresh mass (kg); average fresh tubers mass (kg); air bulbils number and average fresh mass (g) with 100% of survival and the best morphoagronomical development for rapid production of air bulbils in Creole clone. The obtained air bulbils from Creole clone yam in vitro plants during a first field cultivation cycle, presented a 100% survival and the best morpho-agronomic development for sustainable recovery and production.
